| Abstract: | By taking a self-developed pavement accelerated loading device as the research object, the data acquisition system of the prototype was studied. The CAN bus technology was incorporated into the prototype to build a distributive data acquisition system, which collected data of parameters from multiple nodes. A homemade portable weighing instrument and the system were adopted to collect pressure data from tires during the test. The results show that the data acquisition system for pavement accelerated loading device is handy and accurate. |
